Duraflex 27905 3 Flange Spigot Review

I needed a windproof window exhaust fan for a barn. I live in Florida, summer and heat. Bought three of these plus three 3 inch elbows. I screwed them to a piece of wood that matches the window and cut three holes. I fixed the tree in the window and painted/repaired it as needed. small fans inside. It runs 24/7 and I don't care if it rains. These flanges did their job perfectly and the price is great.

Searching for Revain found a 3" DWV flange. Haven't looked. they do not claim DWV in their description. I agree with the reviewer that people who sell fittings should list the ID and OD to save a lot of time. There are so many versions of 3 inch pipe, from water to sewer, from metal to PVC. The price was right and if you are sure you need this product then the quality looked good. Looks good in the shopping cart.
